technical field

The utility model relates to the construction field, in particular to a flat seam waterproof structure of prefabricated wall boards with drainage channels.

Background technique

Compared with the shortcomings of the traditional construction model, such as long cycle, low efficiency, high consumption, and difficult quality control, prefabricated buildings have gained a lot of advantages by virtue of their advantages such as fast construction speed, less labor force, slight pollution, comfortable working environment for workers, and guaranteed quality of components. more and more widely used. With the rise of labor costs, the improvement of workers' requirements for the working environment, the stricter environmental protection requirements and the promotion of national policies, prefabricated buildings have become the trend of future construction development. However, with the continuous expansion of the building area, a series of problems have emerged one after another, especially the waterproofing of the exterior walls of prefabricated buildings. The many hazards caused by it have greatly hindered the promotion of prefabricated buildings. Therefore, engineers and technicians need a flat seam waterproof structure of prefabricated wall panels with drainage channels to improve the waterproof performance between assembled exterior wall panels.
